When i had my sub active I wanted the Thundering Cobalt serpent but I wasn't going to keep my account active just to keep checking everyday. However if they had the Black Proto-Drake on there, I would insta subscribe.
Anyways I got from the BMAH
South Wind Drake
Blazing Drake
Heavenly Onxy Serpent
Blue Drake (it would never drop for me so I just said fuck it and bought it for 30k)
Plagued Proto-Drake
